Fig 5. Comparison between patients and volunteers for aortic distensibility at rest and exercising.

AD = aortic distensibility. AAo = ascending aorta. DAo = descending aorta. *: p = 0.027. ns = non-significant p-value. This result shows a statistical difference between the patients and volunteers on AAo when exercising which does not exist at rest. This suggests that exercise can reveal a decrease in aortic distensibility at an early stage.
